Application filed March 2, 1927. Serial No. 172,173. f r

My invention relates to the classof devices that are employed for shavingolf. the ends of fillings of cork or other material commonly used in most of the clutches, and especially as embodied in automobile construction, and an object of my invention, among 0thers,1s

the production of a device of this class by means of which such fillings may be shaved oft in a particularly rapid and el'ficient manner.

One form of fixture embodying my inyention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in; the accompanying drawings, in which Figure 1 isa top view of a fixture embodying invention. V p v Figure 2 is a view in central cross section through the same.

Figure 3 is a view of a fragment of the base of my improved fixture showing the operation of the clamp for securing a plate or ring in place in said fixture.

In the accompanying drawings the numeral'5 indicates the base of my improved fixture that may be made from any suitable material, preferably metal, this base, as herein shown, being round and having a central opening 6. A groove 7 is formed in the base, extending concentrically therein, and a shelf 8 constitutes a part of said groove on each side thereof. Clamps 9 are pivotally mounted on the shelves, these clamps being supplied in any suitable number, and each clamp has a clamping lip 10, as shown in Figure 3. The under side of this clamping lip is tapered toward one edge forming a cam 11, whereby, as the clamp is rotated on its pivot, said lip will be brought tighter and tighter lnto engagement with a clutch plate or ring 12.

In clutches commonly employed at the present time, the clutch plates or rings 12 are used, and fillings 13 are located 1n holes in said plates of rings. These fillings are commonly composed of cork or similar material and they are driven into'the holes in the rings so that they protrude at opposite sides thereof. The ends of these fillings are then cut off so that they will all be located in the same plane. j

Where the rings are manufactured in quantities this evening off of the ends of the fillings has been done by machinery and in such event it is a comparatively simple matter. However, in garages where comparat vely llttle of this work is required this renewal of the fillings embodying the evening as of the ends,

is somewhat expensive, and it is to overcome this objection and to provide a device bymeausof which this operation may be effected by the ordinaryjgarage worker that this invention has been made. v I i In the operation of the device when the fillings 13 have been secured in place the ring is placed upon the fixture, resting upon the shel'vesS at opposite sides of the groove 7, a boss l t being formed on the fixture and aroundwhich the ring 12mayfit, as shown in Figure 1 of the drawings. I u

The clamps 9 are then brought into tight engagement with the ring'to secure it in place. A knife 15 may now be employed-to shave ofi the'ends of the fillings which will project above the plane of guiding surfaces 16'l7 formedon opposite sidesof the groove 7 these'guiding surfaces being composed of the boss 14 and the outer part of the base bounding the groove 7.

In accordance with the provisions of the patent statutes I have described the principles'of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; :but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out. i

I claim: 7

l. A fixture for supporting a clutch plate during the shaving off of fillings which project beyond opposite facesof aplate, said fixture comprising a base having surfaces for contacting with the plate free of said fillings to support and hold the plate, and a guide surface for the reception of a cutting element located adjacent the aforesaid surfaces.

2. ,A fixture for supporting a clutch plate during the shaving off of fillings which proect beyond opposite faces of a plate, said fixture comprising a base having surfaces for contacting with the plate free of said fillings to support and hold the plate, means for securing the plate against said surfaces, and a guide surface for the reception of a cutting element located adjacent the aforesaid surfaces. c

3. fixture for supporting a clutch plate during the shaving off of fillings which project beyond opposite faces of a plate, said fixture comprising a base having surfaces for contacting with the plate free of said fillings ilo to support the-plate with either lace exposed and to holdthe plate againstlateral-movement, means for releasably clamping the plate against said surface, and aguide sur face for the reception of a cutting element located adjacent'the aforesaid surfaces.

4. A fixture for supporting a clutch plate during the shaving off offilhngs which project beyond opposite faces of a plate, said fixture comprising a basal-raving a'fiat surface formed with a groove toreceive a plate, said groove being-provided -with shelves on opposite sides thereofwhich are raised aproper distance to support the plate with the depending fillings free-from the floor of'the groove and with the upwardly extending filling-s arranged to project above vthe flat face oi the base the amount to be shaved off.

5. A 'fi xture'for supporting a clutch plate during theshaving 01f oflfillings' which project beyond opposite faces-of a plate, said fi'xturecomprislng a baseh'aving a fiat: surface formed a groove to receive a; plate, said groove-being providedwith shelves on opposite sidesthereoi Which-are raised a proper distance to support the plate withthe depending fill ings free from the 'fi'oor *of the groove and with the upwardly extending filli-ngs arranged ,to project above the fiat "face of the'base the amount to be shaved oil,

and means tor clarnpangthe plate against said shelves. 7 *6.
